“…CT is the method of choice to characterize bone changes and may differentiate between osteoid osteoma and chronic osteomyelitis. The role of MRI is controversial because of the variable appearance of the lesion and the reactive changes in the bone marrow and soft tissues [1].…”

A 9-year-old boy presented to the rheumatology consultation with left elbow pain for the prior three months. The pain was associated with swelling, stiffness, and limitation of movement suggestive of inflammation. The blood work was normal. Mono-articular juvenile idiopathic arthritis (JIA) was suspected, and the patient was referred for left elbow ultrasound, which confirmed synovial thickening (arrow on Figure 1A). Treatment with nonsteroidal anti-inflammatory drugs was started, and three weeks later an intra-articular infiltration with cortico-steroids was carried out. Three months later, as the symptoms persisted, a new ultrasound of the elbow was performed, demonstrating joint effusion (asterisk on Figure 1B); elbow radiograph on the same day showed metaphyseal sclerosis (blue asterisk on Figure 2A), peri-articular osteopenia (green asterisk on Figure 2A) and periosteal apposition (arrows

“…Usually OO are small in size between <1.5 and 2 cm and they appear within cortex of the long bones of lower limbs [ 4 ]. Typical clinical presentations of OO are pain that it worsens at night and it is improved by NSAIDS and use of aspirin, but when the OO is inside the joint, it is accompanied with synovitis, limited range of motion, joint effusion, and contractures [ 5 ].…”

In the elbow joint, occurrences of intra-articular osteoid osteoma are uncommon. We detail the case of a 21-year-old male who experienced pain, inflammation, and a restricted ability to move his elbow. For a few months, the diagnoses was missed and the patient was treated for idiopathic synovitis. After a contrast MRI, the tumor was revealed. During an arthroscopic examination of the elbow, a distinct red lesion was observed after the removal of the pale reactive bone in the olecranon cavity. This was subsequently removed in its entirety with the aid of a specialized bone tool. Histopathology confirmed the diagnosis of osteoid osteoma. Remarkably, the individual reported alleviation from the symptoms just a day following the operation and regained full range of motion 5 weeks after the surgery. This case underscores the efficacy of arthroscopy in addressing intra-articular osteoid osteoma, with a focus on accurately pinpointing the lesion.

“…A range of recent studies published in Brazil have highlighted the relevance of imaging methods in the assessment of the musculoskeletal system (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12) . In the present study, the authors evaluate the characteristics of enchondromas at knee magnetic resonance imaging (MRI).…”

Incidental enchondromas at knee magnetic resonance imaging: intraobserver and interobserver agreement and prevalence of imaging findings

et al. 2013

Objective: To evaluate intra-and interobserver agreement in the identification of incidental enchondromas at knee magnetic resonance imaging, and to assess the prevalence of imaging findings. Materials and Methods: Retrospective study reviewing 326 knee magnetic resonance images acquired in the period between November 2009 and September 2010. The images were independently and blindly analyzed by two specialists in musculoskeletal radiology, with the objective of identifying incidental enchondromas, presence of foci with signal similar to bone marrow and foci of signal absence suggestive of calcifications within the enchondromas. Inter-and intraobserver agreements were analyzed. Results: Eleven lesions compatible with enchondromas (3.3%) were identified. The interobserver agreement for the presence of enchondroma was high. Prevalence of foci of bone marrow signal inside the enchondromas was of 54.55%, and foci suggestive of calcification corresponded to 36.36%. The intraobserver agreement for foci of bone marrow signal in enchondromas was perfect, and interobserver agreement was high. Conclusion: The prevalence of incidental enchondromas in the current study was compatible with data in the literature. Excellent agreement was observed in the identification of enchondromas and in the assessment of imaging findings. A higher prevalence of fat signal foci was observed as compared with signal absence suggestive of calcifications. Keywords: Enchondromas; Magnetic resonance imaging; Knee; Bone marrow.Objetivo: Avaliar a confiabilidade intra e interobservador na identificação de encondromas incidentais na ressonância magnética de joelho e estudar a prevalência das características de imagens destas lesões. Materiais e Métodos: Estudo retrospectivo, com revisão de 326 ressonâncias magnéticas do joelho realizadas entre novembro de 2009 e setembro de 2010. As imagens foram analisadas por dois médicos especialistas em radiologia musculoesquelética, de forma independente e às cegas, visando a identificar encondromas incidentais, presença de focos com sinal semelhante à medula óssea e focos de ausência de sinal sugestivos de calcificações no interior dos encondromas. Foram realizadas análises das concordâncias inter e intraobservador. Resultados: Foram identificadas 11 lesões compatíveis com encondromas (3,3%). A concordância interobservador para presença de encondroma foi alta. A prevalência de focos de sinal de medula óssea no interior dos encondromas foi 54,55% e de focos sugestivos de calcificação foi 36,36%. A concordância intraobservador para focos de sinal de medula óssea nos encondromas foi perfeita, e a concordância interobservador foi alta. Conclusão: A prevalência de encondromas incidentais no trabalho atual foi consistente com a literatura. Foi observada excelente concordância no estudo de confiabilidade da identificação de encondromas e de suas características, notando-se maior prevalência de focos com sinal de gordura do que de calcificações. Unitermos: Encondromas; Ressonância magnética; Joelho; Medula óssea. Ab...
